51
Q

In the course of performing a monopolar TURP under spinal block, the nurse anesthetist reports the patient is suddenly markedly confused, brachycardic, and hypertensive. Patient is likely experiencing TUR syndrome; thus rapid termination is needed. The height of the irrigating fluid above the patient should be carefully chosen. Investigators have demonstrated that the ideal height of the fluid was ___ above the patient. This appears to be the minimal height to maintain good vision but also not lead to excessive systemic fluid absorption. Increasing the height ___ above this leads to increased pressure in the prostatic fossa and a greater than twofold increase in systemic fluid absorption. Diagnosis of this condition is made by assessment of neurologic status and comparison to laboratory values. Serum sodium should be obtained in long, large resections postoperatively (or intraoperatively if concern exists). A serum sodium of ___ indicates a significant dilution and may lead to coma or seizures. Transient visual disturbances or blindness indicate central nervous system (CNS) toxicity and are obviously very distressing to all the parties involved. If profound central nervous symptoms are noted, judicious administration of ___ should be instituted and formulas exist to help guide this resuscitation as overly rapid correction of hyponatremia may lead to a___

A

60 cm

10 cm

less than 120 mEq/L

Hypertonic saline

demyelinating lesion of the brain (central pontine myelinolysis).

52
Q

risk factors for TUR syndrome: Failure to use ___, ___ irrigating solution and the bipolar electroresection system

steps to prevent TUR syndrome:

the use of isotonic, iso-osmolar irrigating solution and the bipolar electroresection system this risk has theoretically been eliminated.

While most authors agree that TUR syndrome is caused by dilutional hyponatremia, there have been alternate etiologies proposed. Excessive glycine absorption can lead to liberation of __ from metabolic pathways leading to immediate or delayed encephalopathic symptoms. Several steps can be taken to prevent this complication. Use of a __ resection method should certainly be considered. The __of the irrigating fluid above the patient should be carefully chosen. Use the ___ to maintain good vision but also not lead to excessive systemic fluid absorption.

A

risk: Failure to use isotonic, iso-osmolar irrigating solution and the bipolar electroresection system.

ammonia

bipolar

height

minimal height

53
Q

ETIOLOGY OF TUR SYNDROME: Absorption of non–___-containing irrigating fluid, leading to an acute __. Absorption of non– sodium-containing irrigating fluid into the __ that is exposed during resection is the etiology of the disease. This risk appears to be unique to __; other BPH techniques (such as bipolar TURP, HoLEP, and laser vaporization) use isotonic/iso-osmolar irrigating fluid such as normal saline. The ideal height of irrigating fluid was determined to be __ cm above the patient, as this balanced the benefits of visualization with systemic absorption. Heights above this level will lead to an increased systemic absorption. In general, symptoms of TUR syndrome begin with a serum sodium of ___

A

non- sodium

dilutional hyponatremia

prostatic venous system

Monopolar turp

60 cm above the patient

less than 120 mEq/L.

54
Q

TRUE regarding transurethral incision of the prostate (TUIP)

It may have a ___ of ejaculatory dysfunction in patients when done unilaterally. The procedure is relatively short and does not cause __. The procedure is only appropriate for small prostate glands (generally __), and no prostate adenoma is removed. ___ occurs in up to 37% of patients. Although this is controversial, most authors believe that the risk of retrograde ejaculation is lower if done __ as opposed to bilaterally

A

lower rate

TUR SYNDROME

less than 30 ml

RETROGRADE EJACULATION
